Two Australian citizens convicted of leading a drug smuggling ring have been moved to the high security prison in Indonesia where they are due to be executed. The country's president Joko Widodo insists that he will show no mercy and that no amount of foreign pressure will stop the executions from going ahead.
The case has generated a huge amount of media interest in both Indonesia and Australia, and has been the subject of intense diplomatic wrangling as the Australian prime minister Tony Abbott has sought to have the two men's death sentences revoked.
But who are the men at the centre of the high-level diplomatic negotiations? And why is the Indonesian president intent on carrying out their execution?
Who are the Bali Nine?
In 2005, a group of Australians now known as the Bali Nine were arrested in Denpasar accused of smuggling heroin from Indonesia to Australia.
Andrew Chan, Si Yi Chen, Michael Czugaj, Renae Lawrence, Tan Duc Thanh Nguyen, Matthew Norman, Scott Rush, Martin Stephens and Myuran Sukumaran were subsequently tried and found guilty of attempting to take more than 8.3kg (18lb) of heroin valued at $4 million Australian (£2 million) out of the country.
Most were given life sentences, but Andrew Chan and Myuran Sukumaran were convicted of recruiting for and leading the group and were consequently sentenced to death.
How were they arrested?
Chan and Sukumaran recruited seven Australians to act as drug mules bringing heroine from Bali to Australia in 2005, the court found. Balinese authorities had been tipped off by Australian police and arrested the group as they were preparing to fly back to Australia. Four people were arrested at Denpasar airport with heroin strapped to their bodies, and Sukumaran and three others were found in possession of heroine at a Kuta hotel. Chan was arrested at the airport but was not carrying any drugs.
Did they appeal?
Over the following decade, the group, including Chan and Sukumaran mounted a sequence of legal appeals to have their sentences overturned. Some have had their appeals granted, but Chan and Sukumaran's appeals to have their death sentence overturned have been rejected one by one.
The duo's final hope was to apply for a presidential pardon, which in 2012 appeared to have been accepted by the former Indonesian president Susilo Bambang Yudhoyono after Chan and Sukumaran's names failed to appear on the list of detainees scheduled to be executed in 2013.
However, the following year Indonesia's new president Joko Widodo announced that there would be no mercy for any drug-related crimes and said that he would soon be dealing with a number of appeals for clemency that had been sitting on the presidential desk for some time, the ABC reports. These included those of Chan and Sukumaran, which, at the beginning of this year were officially rejected.
Who are Chan and Sukumaran?
Chan was born in Sydney in 1984, the son of Chinese migrants. He went to school in Sydney and worked as a part-time cook before his arrest in 2005. Prior to his arrest he had been an atheist, but he converted to Christianity while in prison and studied to become a pastor.
Sukumaran was born in London in 1981 but moved to Australia in 1985. He worked in clerical jobs, and held a position at the Australian passport office. He says that he became involved in drug smuggling due to the promise of making quick money. In prison, he has turned his hand to painting and has been awarded an associate degree in fine arts.
What happens next?
According to the BBC's Indonesia editor Karishma Vaswani, the planned executions have "raised tensions between Australia and Indonesia at a time when the two countries were just starting to repair ties after a spying incident".
Lawyers for the two Australian men are still attempting a final legal appeal, but President Widodo insists that all legal and diplomatic pleas are in vain.
"The first thing I need to say firmly is that there shouldn't be any intervention towards the death penalty because it is our sovereign right to exercise our law," Widodo said.
The president has been bullish in his attitude to countries opposed to capital punishment. No date has been set for the executions. Indonesian authorities are obliged to give 72-hours notice before executing prisoners.
